By the way,what i want to do is to validate the email etc,such like if the email field is empty,then it will show errors beside the email textfield..

Member Avatar for diafol

This looks like a case for both client-side and server-side validation. To save time and frustration for your prospective members, you should have js validation to check for errors before the form is sent. Any errors should be noted at the top of the form or on top of /beside the form widget.

Server-side validation (pHp) MUST take place if data is to be passed to DB or even back to HTML. Again, a mechanism should be in place if an error occurs.

This is quite involved and you would do well to get an off-the-shelf js checker (I've used YAV in the past: http://yav.sourceforge.net). pHp reporting is more straightforward:


If you're going to produce your own php validation scripts, you'll need to learn about regular expressions (regexp). Looks horrendous, but ain't that bad.

Thanks a lot...By the way i want to ask your opinion.Which one is better?Put the validation code on a within with the output_fns.php or seperate it??Thanks...

Member Avatar for diafol

If I were you I'd create a new include file for your form validation functions. This way you keep it available for all your form validations.

For example:

In "form_validate.inc.php":

function validate($data_type){
 ...(this is your validation script)...
 ...it should return true or false...
 ...(this is the simplest validation function, it could be developed to be far more complex)...

In your form handler:

$date_valid =validate($_POST['mydate']);

This ain't particularly clever code, but you get the idea. If you Google 'php form validation' you should get loads of good hits.
